SPECIFICATION forming part of Letters Patent No. 746,222, dated. December 8, 1903.

Application filed July 16, 1902. Serial No. 115,744. (No specimens.)

To all whom it may concern:

Be it known that I, FBANZWINDHAUSEN, Jr.,engineer, asubject of the King of Prussia, Emperor of Germany, and a resident of No. 1 Oorneliusstrasse, Berlin, W., in the Kingdom of Prussia and Empire of'Germany, have invented an Improved Process of Regulating the Supply of Fluids, of which the following is a specification. i

The present invention relates to a process for regulating theflow of waste steam to the Vaporizers of cold-steanipower machines.

In a vaporizer of a cold-steam-power engine heated by the Waste steam of a steam-engine it may happen that according to load of the steam-engine and the motor heated by the same sometimes more and sometimes less waste steam is conducted to the latter than is necessary for the heating. If now more waste steam is present than is required,then according to the present invention only so much steam shall be conducted to the vaporizer as is required to heat the same and for the attainment of a normal pressure of the produced cold vapors, while the excessive portion of the steam without passing the vaporizer passes through a suitable device in'to'the atmosphere or into a surface or jet condenser and to there give up its heat. The device-for leading off the excessive portion of the waste steam may be a valve,a cock, a slide, athro't; tle-valve, or the like, and should be opened as soon as the pressure of the waste'steam or that of the generated working (cold) steam exceeds the 'normal that is to say, as soon as more heat flows to the vaporizer than is required or necessary for the normal heating of the same-and should be closed as soon as the pressure of the waste'steam or the working steam is less than the normal, as then less heat passes in the waste steam to the vaporizer than the same requires. The opening and closing of the device for conducting away drawing, which is a sectional elevation of a plant embodying my invention.

This automatic regulation may,forinstance, be carried out by the apparatus a, (shown in the accompanying drawing) in which the changing pressure of the working steam is employed to efiect the opening and closing of the pipes for the excessive waste steam, it being assumed that the waste steam thus steam flows through the pipe Z into the apparatus a and can pass from here to the vaporizer b. of the cold-steam motor, as also to the condenser c, inwhich cooling-water circulates through the pipe 2 and 3. The feed of the waste steam to the vaporizer is, as a rule, open and may be regulated by the slide (1, while the flow of the waste steam to the coudenser o is regulated by the slide 6, which is, as a rule, closed. Both slides are in direct or indirectconnection with a membrane f, upon the one side of which the pressure of the cut ofl passes into a condenser c. The waste working vapors generated in 1) acts through thetube 4, the pressure ofthe working steam upon the membrane being taken up by the adjustable spring g.

At the normal pressure of the Working steam upon the'membranefthe slides 01 6 take up approximately the normal position shown and the entire quantity of the waste steam flowing through the tubel passes through the open slide (1 into the vaporizer b in order to here give up its heat for the generation of g. In consequence of the giving up of heat the tube 6 into the atmosphere or to an airpump.

by the vaporizer b, the pressure of the waste steam and that of the generating working steam becomes greater than the normal, the pressure on the membran-ef then becomes greater than the counterpressure of the spring g, the slide 01 and e will change their position and by means of the slide (1 will check or entirely stop the flow of the'waste steam to the vaporizer b, while the excessive portion of the waste steam not required in the vaporizer will pass through the open slide 6 into the atmosphere or. through the tube 7 into the condenser c, and in the latter will be condensed by cooling-water; The condensed waste steam passes through the tube 8 into the atmosphere or to an air-pump. As soon as the consumption of heat in the vaporizer b is working steam which flows through the tube the waste steam condenses andpasses through IE'more waste steam enters than is required again greater than corresponds to the abovementioned checked flow of steam through the slide cl and the tube 5 the pressure of the working steam upon the membrane fdrops, and in consequence of the pressure of the spring the slides d and e are so actuated that by means of the slide 6 the discharge of the Waste steam to the condenser c is closed, so that the whole of the waste steam passes through the slide (Z and the pipe 5 into the Vaporizer.

I desire it to he understood that various modifications may he made and equivalents used without departing from the nature of my invention.

What I claim, and desire to secure by Letters Patent of the United States, is

The herein-described process of regulating
